I'm no scientist, but something clearly is going on.While many environmentalists point to increased storm activity as a sign of global warming, my concern has been with water temperatures. They're rising in the Northeast, and that's not healthy for fish stocks. (The North Atlantic must be under 45 degrees in order for the stocks of key species to thrive.

Over the last year or so, haddock and cod stocks appear to be shrinking. At first, some environmentalists accused fishermen of overfishing. But that couldn’t be the case, as the catch limits are already very stringent. There simply had to be a better reason for the precipitous drop-off.

Now scientists and fishermen are beginning to acknowledge that the declines aren’t caused by the amount we've harvesting, but by water temperatures. But is the water temperature causing fish to just disappear? Interestingly, no.They are migrating to colder waters.

Iceland and Norway are actually benefiting from this migration of species.Some of our folks recently returned from Scandinavia, and reported that the harvest of cod and haddock has been robust. Meanwhile, landings are expected to continue tightening here in the North Atlantic over the next year.Don't be shocked to see higher menu prices for locally-caught haddock and cod, as well as for day boat fish, flown in fresh from Scandinavia.

And while this is primarily bad news, there could very well be a silver lining for those of us who enjoy lobster. Cod is one of the natural predators of lobster - they traditionally feed on lobster larvae and eggs.With cod disappearing from the warmer waters, we may see a bumper harvest of lobster this summer.
